Try running Disk Cleanup on your server. You may have to install this through the features menu. <br />

There is an option in Disk Cleanup to clean up System Files. This might clean up some space.

Disk cleanup needs to be installed though the desktop experience package, which puts a ton of junk on the server, i don't recommend it.

I think you might be able to install just what you need. Disk Cleanup is a very good Microsoft offering for removing old (system) files without damaging anything.

often running a diskcheck on the drive fixes these problems<br />
so that's my suggestion - run chkdsk

What was the actual solution? why was my suggestion of it being shadow copies or backup data worse than noxcho or Predrag Jovic?

Frank, yes sorry your suggestion about shadow copies was helpful. &nbsp;I followed noxcho's instructions to view and delete the shadow copies instead of enabling/disabling them and this cleared up 192GB of disk space.<br />
<br />
Is there a way to go back and add to the Accepted Solutions?

Windows Server 2008 hard drive says it's full, but it's not

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.
